On a site that is protected by an SSL certificate, attackers cannot intercept personal data of visitors: logins, passwords, bank card data and other information. An SSL certificate guarantees their protection. Let’s recall how at one time the Google search engine announced that it would increase the search results of sites that switched to the HTTPS protocol, which gives an undeniable advantage for SEO. Yandex also did not stand aside and mentioned the advantages of using an SSL certificate in his blog. So the days of the insecure HTTP protocol are a thing of the past.

It is easy to identify a site with an SSL certificate – if you see a small lock next to the site address in the browser, then the site is protected, and all information is transmitted over the secure HTTPS protocol.

Companies that issue SSL certificates are called certification centers, which, in turn, are divided into commercial and non-commercial.

For example, the non-profit certification center Let’s Encrypt issues completely free and automated certificates that protect websites no worse than paid analogues. The main difference between a paid certificate and a free one is a financial guarantee. In case of hacking of a paid certificate, the certification center can pay compensation. Sometimes, these are very substantial sums, from $ 500K and above.
